I have programmed a game like Break Out, i want to make a lifecounter so, if the ball hits the bottom the "3 lifes" get -1, and when this happends the text should display "3 lifes"... look at my code and tell me whats wrong PS: Im german so "Leben" means "lifes" and "spielball" is the object from the ball: 
public byte c=3;
---------------------
public void lifecounter(){
        if(c == 3){
            showText("3 Leben",300,500);
        }
        else{
            if(c == 2){
                showText("2 Leben",300,500);
            }
            else{
                if(c == 1){
                    showText("1 Leben",300,500);
                }
                else{
                    if(c == 0){
                        showText("GAME OVER",300,500);
                        Greenfoot.stop();
                    }
                }
            }
        }
    }
-----------------------
 public void lifemachine(){
         if(spielball.getY() > 780){
            c--;
        }
    }

After line 27, you need to call 'lifecounter' to update the text.

like this? : if(spielball.getY() > 780){ c--; lifecounter();}

Yes. You need to execute the line of code which changes the display. Just changing the variable 'c' won't change the counter unless the 'lifeCounter' method is always being called (in the 'act' method).
